seen from above. 



The lower articular surface of the radius is divided by a ridge 

 into two halves, for articulation with the scaphoid and semilunar bones ; 

 the under surface of the Cartilago inter articular is , which is situated bet-

from above. 



The upper surfaces of the three external of the first row of carpal 

 bones are convex, smooth and covered with cartilage, for articulation with 

 the lower extremities of the bones of the forearm. The articulation bet-
